Description

TECHNICAL FIELD

[0001] The application relates to the field of split charging piles, in particular to a split charging pile with high heat dissipation. BACKGROUND

[0002] The strong current input and rectification part of the split direct-current charging pile system are separated, only the communication control and direct-current output part are provided at the user end, the charging pile is reduced in size and cost, and the risk of electric shock of the user is avoided; the user terminal is small in size, light in weight, convenient to move and replace parts, and high in space utilization, and can be widely applied to various communities.

[0003] However, when the split charging pile is installed and used in the community, the temperature of the gun line of the user end charging pile obviously rises after high-power and long-time charging, when the rising temperature triggers the over-temperature protection mechanism of the user end charging pile, the user end charging pile will be forced to stop charging, and the charging pile cannot be used again until the temperature drops to a safe value, thereby reducing the efficiency of subsequent charging with the charging pile, and therefore, a charging gun with an auxiliary heat dissipation device is needed to solve the high temperature problem of the traditional split pile during high-power charging. CONTENT OF THE INVENTION

[0004] In order to facilitate auxiliary heat dissipation of the charging gun line, a split charging pile with high heat dissipation is provided.

[0005] The above application purpose of the application is realized through the following technical scheme:

[0006] The split charging pile with high heat dissipation comprises a pile body and a cable, one end of the cable is fixed with a charging gun, and further comprises a cooling mechanism, the cooling mechanism comprises a cooling box containing cooling liquid and circulating pumps located on both sides of the cooling box, the number of the cables is two, and one end of each of the two cables away from the charging gun is connected to the two sides of the cooling box in communication, and the circulating pumps drive the cooling liquid to be transmitted through the cables and the charging gun.

[0007] Through the above technical scheme, when the charging gun is used to charge the electric vehicle, the temperature of the charging gun and the cable will rise, the circulating pump will drive the cooling liquid to be delivered to the cable and the charging gun, when the cooling liquid flows through the cable and the charging gun, the cooling liquid will take away the heat generated by the cable and the charging gun, and then the cable and the charging gun are cooled, and two charging guns with liquid cooling technology can more effectively disperse and manage heat, two charging guns can work independently or cooperatively, and the different parts of the pile body are accurately cooled, so that the heat accumulation and the formation of hot spots are avoided, and the heat dissipation efficiency of the whole system is improved.

[0008] Optionally, two radiators are installed on each side of the cooling box, and the distribution direction of the two radiators is perpendicular to the cooling box.

[0009] By adopting the above technical solution, the heat of the cooling box can be quickly conducted away by the high thermal conductivity of the radiator, which can more effectively dissipate the heat inside the charging pile. At the same time, the liquid cooling combined with the design of two radiators can usually produce lower noise, providing users with a quieter charging environment.

[0010] Optionally, the cooling mechanism further includes two cooling fans, both located on one side of the pile body, and each located on one side of a radiator.

[0011] By adopting the above technical solution, two cooling fans are added. The two cooling fans dissipate heat from the two radiators separately, enabling the radiators to transfer heat to the outside more effectively, which can quickly reduce the temperature of the equipment and enhance the heat dissipation effect of the radiators.

[0012] Optionally, the cooling fans are configured as two sets, with the two sets of cooling fans fixed on both sides of the pile body respectively.

[0013] By adopting the above technical solution, two sets of fans are installed on both sides of the pile body to form good air convection, draw in cold air and pass it through the radiator to remove the internal heat, ensuring that the heat can be discharged in time.

[0014] Optionally, a support seat is installed on each side of the pile body, the support seat is located at the bottom end of the pile body, and the support seat is hinged to the pile body.

[0015] By adopting the above technical solution, when the charging gun is installed on the pile, part of the cable will fall to the ground. The mounting base can be lowered and the cable placed on the mounting base, which can reduce the friction and collision between the cable and the ground or other objects, reduce the possibility of cable damage, reduce the risk of people tripping over the cable, and improve the safety of use.

[0016] Optionally, a tower buckle is fixed on the side of the mounting base facing away from the cable, and fixing posts are fixed on both sides of the pile body, with the tower buckle and the fixing posts fastened together.

[0017] By adopting the above technical solution, the scaffolding can be lowered more conveniently to support the cable when in use; when not in use, the scaffolding can be fixed to the fixed post by using a tower buckle, which reduces the space occupied by the pile in some environments with limited space.

[0018] Optionally, a gun holder that engages with the charging gun is installed on the side of the pile body. A wire harness assembly is provided on the outer periphery of the gun holder. The wire harness assembly includes a wire harness ring, and the cable is wrapped and placed on the wire harness ring.

[0019] By adopting the above technical solution, the cable is wrapped and placed on the cable tie ring, which can prevent the cable from getting tangled or scattered on the ground, reduce the mess near the charging station, make the charging environment more tidy and orderly, prevent the cable from stretching on the ground, reduce the risk of people tripping over the cable, and improve the safety of use.

[0020] Optionally, the wire harness assembly includes a baffle, one end of which is fixedly connected to the wire harness ring, and the other end extends upward.

[0021] By adopting the above technical solution, after the cable is stored on the cable tie ring, the baffle limits the cable to prevent it from stretching out and falling off the cable tie ring, ensuring that the cable can be stably wrapped on the cable tie ring.

[0022] Optionally, the cable assembly further includes a limiting plate, one end of which is fixedly connected to the cable ring, and the other end extends upward, with a limiting groove formed at the extended end. The charging gun includes a gun head and a gun tail. The width of the gun head perpendicular to the cable ring is greater than the distance between the two walls of the limiting groove, and the gun tail can pass through the limiting groove.

[0023] By adopting the above technical solution, most existing charging gun storage devices lock the charging gun onto the buckle of the pile body to limit its position. However, the locking force of the buckle will gradually decrease after repeated use, eventually making it unable to lock the charging gun. When the buckle fails to lock the charging gun, it will fall off the pile body. The limiting groove can lock the gun head, ensuring a more stable connection between the charging gun and the pile body and avoiding inconvenience and loss caused by falling off.

[0024] In summary, this application has at least the following beneficial effects:

[0025] 1. Two charging guns with liquid cooling technology can more effectively disperse and manage heat. The two charging guns can work independently or in combination to precisely dissipate heat from different parts of the charging station, thereby avoiding heat accumulation and the formation of hot spots, and thus improving the heat dissipation efficiency of the entire system.

[0026] 2. When the charging gun is not in use, the cable tie and support can be used to store the cable, reducing friction and collision between the cable and the ground or other objects, reducing the possibility of cable damage, and also reducing the risk of people tripping over the cable, thus improving safety.

[0032] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0033] As attached Figure 1 and attached Figure 2 As shown, a split-type charging pile with high heat dissipation includes a pile body 1, a cable 2, and a cooling mechanism 4.

[0034] Cable 2 is located on both sides of pile 1. One end of cable 2 is connected to pile 1, and the other end is fixed with charging gun 3. Charging gun 3 includes gun head 31 and gun tail 32. Gun tail 32 is connected to one end of cable 2.

[0035] The two sides of the pile body 1 are equipped with gun seats 11 that are engaged and connected to the gun head 31 of the charging gun 3. The gun seats 11 are fixedly connected to the two side walls of the pile body 1. The outer periphery of the gun seats 11 is provided with a wire harness assembly 12, which includes a wire harness ring 121 and a limiting plate 123.

[0036] The cable tie 121 is ring-shaped, and there are two cable tie 121s. The two cable tie 121s are located on the outer periphery of the two gun seats 11 respectively. The outer periphery of the cable tie 121 is used for the cable 2 to be wrapped and placed. One side of the cable tie 121 is fixedly connected to the pile body 1, and the upper end of the other side is fixed with a baffle 122. One end of the baffle 122 is fixedly connected to the upper end of the cable tie 121, and the other end extends upward. The baffle 122 limits the cable 2 to prevent the cable 2 from stretching out and falling off the cable tie 121, and ensures that the cable 2 can be stably wrapped on the cable tie 121.

[0037] One end of the limiting plate 123 is fixedly connected to the lower end of the wire harness 121 on the side opposite to the pile body 1, and the other end extends upward, with a limiting groove 1231 opened on the extended end. The tail 32 of the charging gun 3 can pass through the limiting groove 1231. After long-term use, when the fastening force between the head 31 of the charging gun 3 and the gun seat 11 decreases and the insertion becomes unstable, the limiting plate 123 can lock the head 31 of the charging gun 3 to avoid inconvenience and loss caused by falling off.

[0038] As attached Figure 1 and attached Figure 3 As shown, the cooling mechanism 4 includes a cooling tank 41 located inside the pile body 1 and fixedly connected to the bottom end of the pile body 1. The cooling tank 41 contains coolant 411, which is a mixture of water and ethanol, a common product in the field. Two cables 2 are connected to the two sides of the cooling tank 41 respectively. Two circulation pumps 42 are also fixed on the two sides of the cooling tank 41. The two circulation pumps 42 deliver the coolant 411 in the cooling tank 41 to the two cables 2. When the coolant 411 flows through the cables 2 and the charging gun 3, it carries away the heat in the cables 2 and the charging gun 3, thereby cooling the cables 2 and the charging gun 3. At the same time, the two charging guns 3 can work independently or in concert to avoid heat accumulation and improve the heat dissipation efficiency of the entire system.

[0039] The cooling mechanism 4 also includes a mounting frame 43, a radiator 44, and a cooling fan 45.

[0040] The fixing frame 43 is located inside the pile body 1 and is fixedly connected to the bottom end of the pile body 1. There are two fixing frames 43, which are located on both sides of the cooling box 41 respectively.

[0041] There are two radiators 44, which are fixedly connected to two fixed frames 43 respectively. The radiators 44 are metal radiators, and the heat conduction of the metal radiators 44 is faster, which can cool the cooling box 41 more quickly.

[0042] The cooling fans 45 are set in two groups, with two cooling fans 45 in each group. The two cooling fans 45 in the same group are located on one side of the two heat sinks 33 respectively. The two groups of cooling fans 45 are fixed on both sides of the pile body 1. The two groups of cooling fans 45 simultaneously dissipate heat from the two heat sinks 44, and the two groups of cooling fans 45 form air convection between themselves and the two heat sinks 44, which can dissipate heat from the cooling box 41 more quickly and improve the heat dissipation effect.

[0043] As attached Figure 1 and attached Figure 4As shown, a mounting base 13 is provided on both sides of the pile body 1. The mounting base 13 is plate-shaped and located at the bottom of the pile body 1. One end of the mounting base 13 is hinged to the pile body 1, and the cable 2 can be placed on the mounting base 13. A buckle 131 is fixed on the side of the mounting base 13 facing away from the cable 2, which can reduce the friction between the cable 2 and the ground and reduce the risk of people tripping over the cable 2.

[0044] Fixed columns 14 are also fixed on both sides of the pile body 1. One end of the fixed column 14 is fixedly connected to the pile body 1, and the other end extends horizontally away from the pile body 1. When the erection seat 13 is raised, the buckle 131 on the erection seat 13 can be fastened to the end of the fixed column 14. When the erection seat 13 is not in use, it can be folded up, reducing the space occupation rate of the pile body 1.

[0045] The effect of this embodiment:

[0046] Two charging guns 3 with liquid cooling technology are used. The two charging guns 3 can work independently or in concert to precisely dissipate heat from different parts of the pile body 1. At the same time, the heat dissipation required by the two charging guns 3 is achieved by using two radiators 44 to dissipate heat from the cooling box 41, so that the heat generated by the cooling box 41 can be transferred to the radiators 44 more quickly. Two sets of cooling fans 45 are used to dissipate heat from the two radiators 44 at the same time. The two sets of cooling fans 45 form air convection between the two radiators 44, which can dissipate heat from the cooling box 41 more quickly, so that the radiators 44 can transfer heat to the outside more effectively.

[0047] Meanwhile, when the charging gun 3 is not in use, the cable tie 121 and the mounting base 13 can store the cable 2, reducing friction and collision between the cable 2 and the ground or other objects, reducing the possibility of damage to the cable 2, and reducing the risk of people tripping over the cable 2, thus improving safety.

[0048] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
